The Voice wraps up season 8 on Tuesday night, creating a singy void in NBC, but let coach Christina Aguilera ease the pain with a slew of impressions. The singer’s comic chops aren’t what sold her tens of millions of records, but she displays a couple of solid bits of mimicry. Faux Britney Spears with the airhead persona is spot-on, whereas Aguilera’s run at Miley Cyrus feels tacked on particularly superficial. She nails her take on Cher, the haughtiness shining through the big hair and a revealing outfit. See how Aguilera fares trying out Sia, Lady Gaga, and fellow Voice judge Shakira.
